Title: Router element for routing messages in a processing system
Inventor: KRAUSE JOHN C
IPC: H04L69/40
Filed: 1996-06-06
Abstract: A multiprocessor system includes a number of sub-processor systems, each substantially identically constructed, and each comprising a central processing unit (CPU), and at least one I/O device, interconnected by routing apparatus that also interconnects the sub-processor systems.  A CPU of any one of the sub-processor systems may communicate, through the routing elements, with any I/O device of the system, or with any CPU of the system.           Communications between I/O devices and CPUs is by packetized messages.  Interrupts from I/O devices are communicated from the I/O devices to the CPUs (or from one CPU to another CPU) as message packets.           CPUs and I/O devices may write to, or read from, memory of a CPU of the system.  Memory protection is provided by an access validation method maintained by each CPU in which CPUs and/or I/O devices are provided with a validation to read/write memory of that CPU, without which memory access is denied.

Inventor: RODEN JAMES S
IPC: F24H9/00
Filed: 1993-12-13
Abstract: A sacrificial anode assembly is insertable into a metal water storage tank to inhibit corrosion thereof and includes a cylindrical metal anode member having an end retained within a cylindrical plastic insulating sleeve which, in turn, is captively retained within a metal cap portion of the assembly. To regulate the amount of electrical current generated by the assembly during use thereof, a barrel-shaped resistor is supported within the assembly and interconnected between its anode and cap portions. The insulating sleeve has a generally U-shaped groove formed in a closed end thereof, with one leg of the groove extending diametrically across a central opening in the sleeve end that receives a core wire portion of the anode member, and the other groove leg extending generally chordwise relative to the sleeve end. The resistor body is received within the chordwise groove leg, and a lead wire of the resistor is extended through the curved and diametrically extending groove portions and spot welded to the core wire portion received in the central sleeve end opening. The configuration of the groove and the relative orientation of the resistor and sleeve opening causes the bent lead wire to form a resilient connection between the spot weld and the resistor body, thereby substantially reducing vibrational fatigue stress on the spot weld during shipping and handling of a tank having the anode assembly operatively installed thereon.

Title: Tape printer
Inventor: WATANABE KENJI
IPC: B41J3/46
Filed: 1995-11-29
Abstract: The present invention aims to produce a label which has a size, margins and a character arrangement as a user desired, and aims to reduce a wasteful consumption of tape .      In a tape printing device of the present invention, there is established an enlargement printing mode in which a large pseudo label, whose width is wider than the width of tape, can be obtained when the tape is divided into division portions in the longitudinal direction of the tape and when the division portions are arranged in the direction of the width of the tape. When printing in this mode, the tape printing device prints not only a character string but a marker which indicates the dividing positions in the longitudinal direction of the tape, with the intention of improving the quality of the pseudo label.      Further, the tape printing device of the present invention has the function of automatically setting the length of the front and rear margins according to the width of the tape and the function of printing a square-array dot pattern on a wide region which is wider than the character string. Moreover, the tape printing device of the present invention has the function of feeding the tape, for example, between a print head and a cutter, when instructing to stop printing the character string, without printing characters. Furthermore, the tape printing device of the present invention has the function of printing a character string even when accelerating and decelerating a tape feeding motor. Thus, desirable margins or the like can be realized and the reduction in wasteful consumption of the tape can be achieved by making use of theses functions.      Additionally, the tape printing device of the present invention has the function of inputting, taking in and printing (1/M)-scale reduced numeric characters, each of which has a size that is (1/M) the size of a full-size character. Thus, the variety of the manners of printing numeric characters can be increased.

Inventor: HAYDEN RICHARD A
IPC: B01J21/18
Filed: 1995-03-29
Abstract: A method is provided for the restoration of catalytic activity in deactivated nitrogen-treated carbon catalysts. Nitrogen-treated carbon catalysts are those carbonaceous chars which have been subjected to nitrogen-containing compounds at temperatures above about 700.degree.C. These nitrogen-containing compounds can be present either as part of the char raw material or as an additive to the char at any point during its manufacture. The method provides for a means to restore catalytic activity which is largely independent of the mechanism by which deactivation of the catalyst sites occurs. In the present invention, the deactivated nitrogen-treated carbonaceous char is heated to temperatures greater than 700.degree.C, followed by cooling in an inert atmosphere. While at temperatures above 700.degree.C, the char can be exposed to gasifying agents such as steam, carbon dioxide, or oxygen.

Title: Bitmap comparison apparatus and method
Inventor: ABRAMS KENNETH ALAN
IPC: G06T7/00
Filed: 1997-05-27
Abstract: A bitmap comparison technique that is able quickly to compare two bitmap images while discounting differences between the images likely due to noise.  The bitmap comparison technique includes the operations of: comparing the first and second bitmaps, producing a difference map identifying differing bits between the first and second bitmaps, producing outline masks based on the outlines of the first and second bitmaps, identifying certain very different bits within the difference map that are to be weighted differently from the remaining bits within the difference map based upon the outline mask, and determining a comparison score to indicate the extent to which the first and second images differ by differently weighting the very different bits and the remaining bits.  The certain bits are normally weighted to a lesser extent than the remaining bits when determining the comparison score so that the influence of noise in the comparison score is diminished.  The above bitmap comparison technique can be implemented in numerous ways, including as an apparatus, a method or as a computer-readable medium.
